I found the AniMove plugin for QGIS to do the Home Range Analysis for Dolphins.
I load all the points of the sighting, and perform the task using the plugin. I got the contour as polyline, and heatmap as raster. But I have trouble understanding the meaning.
No matter what Utilization Distribution value I input in the parameters box, I get the same contour lines.
And I don't know what is the value in raster means. I tried to check the source code. It seems that the value is estimated by kernel-density estimate using Gaussian kernels. And the z value is further modified by Z = Z.clip(0) * 100.0 / Z.max().
Another user asked something similar as QGIS - Animove - how to show specific kernel density contours? where he asked how to show specific kernel density contours.
